Why does my belt keep shredding?
Believe it or not, this issue happens more frequently than you might believe. In most cases, it’s caused by the tensioner pulley being slightly misaligned. When you replace the serpentine belt, it’s important to align the pulley with the right tools; such as a serpentine belt removal tool and pulley alignment wrench.
What would cause a new serpentine belt to break?
Serpentine belts can fail in a few different ways. This is usually the result of a belt in poor condition, or a problem with one of the accessory components being driven by the belt. A failed bearing in a pulley being driven by the serpentine belt will also cause the belt to break.
Where is the serpentine belt on an engine?
The serpentine belt on an engine is driven by a pulley on the front of the crankshaft, which protrudes out of the front of the engine. Surrounding the protruding end of the crank where it sticks out from the engine block is something called the crank seal, or more precisely the “front main seal.”
What causes a serpentine belt to get stuck?
The main reason, in most cases, will be a stuck pulley from one of the devices (alternator, AC compressor, power steering pump etc) or a tensioner. A stuck pulley is mostly caused by a worn out bearing. The belt slides over a motionless pulley causing extensive friction, heat and the recognizable sound.
Can a serpentine belt cause a BMW to self implode?
Much worse, the belt causes the motor to jump timing and self-implode. No one wants that, so be sure to check behind the crankshaft pulley for belt fragments. If the belt wrapped around the backside of the pulley, remove it and carefully inspect the front main seal.
Is it normal for the crankshaft pulley to be stuck?
Q: Is it normal for the crankshaft pulley to be stuck if the car is off. The serpentine belt is removed. Recently my serpentine belt slipped off while driving. The car is parked and it is cold. I have removed the belt and inspected all of pulleys. I noticed that the pulley for the water pump seems to be a little bit rough, which I will replace.
